The machine disclosed in the above-mentioned Letters Patent is capableof operating upon shoes of widely different sizes, and for this purposenot I only is it provided with means for adjustably varying the limit ofmovement of the heel-lasting wipers, but the wipers themselves havedetachable forward end portions which may be removed in operating onshoes of very small sizes. The wipers, including these detachable endportions, are provided, moreover, with means for driving fastenings fromthem into the shoe bottom to fasten the upper in lasted position. Thewiping edges of the end portions of the Wipers may be curved inwardlylengthwise of the 5 shoe at their forward ends, so that in the wipingoperation they tend to draw the margin of the upper rearwardly and thusprevent it from being pushed forwardly and bulged upwardly in front ofthe wipers. If the wiping edges are curved in this manner, there may bedanger under some conditions that the end portions 08 the wipers at theopposite sides of the shoe will engage each other before the wiperscomplete their wiping movements, with resulting damage to the machine.

An object of the present invention, among 1 others, is to avoid suchdanger of damage to a machine in the operation of end-lasting wipers.The invention accordingly provides wipers of novel construction havingat their forward ends wiping members which are yieldable laterally ofthe shoe relatively to other portions of the wipers. In the constructionherein shown such laterally yieldable end-wiping members are supportedon other end-wiping members which are yieldable heightwise of the shoeas and for the purpose disclosed in the previously mentioned LettersPatent, and the laterally yieldable members are further yieldableheightwise of the shoe with these other members. The use of suchlaterally yieldable members in a machine of the character disclosed, forexample, in the above-mentioned Letters Patent permits the detachableend portions of the wipers to be left in place in operating on verysmall shoes in case it is desired to drive more fastenings than areprovided for by the main portions of the wipers, and in any event servesto insure against damage to the machine if the operator fails to removethe detachable end portions when the wipers are adjusted for 5 verysmall shoes.

The above and other features of the invention, including various noveldetails of construction and. combination of parts, will now be moreparticularly described by reference to the accom- 10 panying drawingsand pointed out in the claims.

The form of wipers shown in Figs. 1 to 5, inclusive, comprises wiperblocks I and 3 similar to the blocks 33 shown in the previouslymentioned Letters Patent, these blocks having detachably secured totheir forward ends, by screws 50 5 and dowel pins 1, end pieces 9. Theseend pieces carry wiping members ll provided with upwardly extendingstems l3 slidingly mounted in the end pieces, the members ll beingpressed down toward the shoe bottom by springs I5 55 Fig. 4) in the endpieces. Downward movement of the stem I3 is limited by pins II extendingthrough the stems and engaging the end pieces. The wiping members II canthus yield upwardly in the same manner and for the same purpose as themembers 63, 68 shown in the above-mentioned Letters Patent. The endpieces 9 and the wiping members II have in them driver passages I9 andspring-pressed balls 2| which retain tacks fed down passages in the endpieces into the driver passages, as also disclosed in the prior LettersPatent.

For purposes of this invention each wiping member II has secured to it ablock 25 having a projection 21 (Fig. 5) which enters a recess 29 in themember I I. A screw 3| extending through a hole 33 in the member II andthreaded in the block 25 holds the block in place. Each wiping member II has formed in it a vertical bore 35 in which is rotatably mounted astem 31 extending from another wiping member 39. The member 39 and theblock 25 have in them cylindrical recesses 4|, 43 (Fig. l) which receivea spring 45 normally holding a face 41 on the member 39 against a stopface 49 on the member II. Each member 39 has a wiping face 5i (Fig. 5)provided with a rounded work-engaging edge 53 which, when the faces 41,49 are in engagement with each other, forms a continuation of a roundedwork-engaging edge 55 (Fig. 1) on the wiping member I I. It will be seenthat the edges 53 are also curved inwardly widthwise of the shoe indirections toward the toe end of the shoe. Each wiping member 39 has alip 51 which engages the upper face 59 (Fig. 4) of the wiping member IIto prevent the member 39 from dropping away from the member II and tomaintain the work-engaging faces of the two members in the samehorizontal plane. It will be evident that the two members are yieldableupwardly together against the resistance of the spring I5 in the wipingoperation. Outward yield of each member 39 against the resistance of thespring 45 is limited by engagement of a lug 6! on the block 25 with thebottom of a recess 63 in the member 39. The springs 45 are strong enoughto prevent the members 39 from yielding in wiping over the margin of theupper.

The modified construction shown in Figs. 6 to 10, inclusive, isassociated with wiper blocks similar to those shown at I and 3 inFig. 1. Each of these wiper blocks has secured to it by a screw and adowel pin an end piece I9, and each end piece has'slidingly mounted init a stem I2 extending vertically from a wiping member 14 which ispressed downwardly by a spring I6 in the end piece. Downward movement ofeach member I4 is limited by a pin I8 extending through the. stem I2 andengaging the end piece I9. The wiping members I4 can thus yield upwardlyin the same manner as the members I I of the first-describedconstruction. Each end piece I9 and member I4 are provided with driverpassages 89 and also with tack-retaining means as in the firstconstruction. Each member I4 has formed integral with it a block 82similar in shape to the detachable block 25 of the first construction,and has within it a vertical bore 84 to receive a vertical stem 86extending from a wiping member 88. Each member 88 has therein a recesswhich receives one end of a spring 99 the other end of which lies in arecess in the block 82. The spring 99 normally holds a face 92 on thewiping member 88 against a stop face 94 on the wiping member 14. Thebore in. the block 82 is so formed that the spring 99 may be insertedafter the wiping member 88 has been assembled with the member I4, and apin 95 (Fig. 9) is provided in the block 82 for one end of the spring toabut against. Each wiping member 88 has a wiping face 96 provided with arounded workengaging edge 98 which, when the faces 92 and 94 are held inengagement with each other by the spring 99, forms a continuation of arounded work-engaging edge I99 on the wiping member I4. The edge 98 isalso inwardly curved similarly to the edge 53 in the first-describedconstruction.

The wiping member 88 is prevented from moving downward relatively to thewiping member I4 by a plate I92 which has in it a dovetailed guide I94for engagement with a dovetailed guide I96 on the wiping member 88. Theplate I92 is secured to the wiping member 88, after the latter has beenassembled with the member I4, by a screw I98 inserted through a hole H9in the plate and into a threaded hole H2 in the member 88. A face H3(Fig. 10) on the plate I92 and a face II4 on the member 88 engagerespectively upper and lower faces on a projecting portion H6 of themember I4, and while permitting the member 88 to swing about the axis ofthe stem 86 prevent upward and downward movements of the member 88relatively to the member M. It will thus be seen that in the modifiedconstruction the wiping member I4 and the block 82 are formed as asingle part, instead of as two parts, and that there are two parts 88and I92 instead of a single part.

From the foregoing description it will be readily understood that if,for operation on a shoe of small size into which it is desired to drivemore tacks than the wiper blocks I and 3 provide for, these blocks andwith them the end pieces 9 or I9 have been so adjusted that in thewiping operation the wiping members 39 or 88 come into contact with eachother, these members will yield against the resistance of the springs 45or 99 and no damage to the machine will result. Likewise no damage willresult if the operator should omit to remove the end pieces in operatingupon a shoe of small size into which are to be driven only the number oftacks provided for by the wiper blocks I and 3.

The laterally yieldable wiping members 39 or 88 have been described asapplied to end pieces each provided with two tack driver passages andwith an upwardly yieldable wiping member II or I4, but it should beunderstood that such laterally yieldable wiping members may be used inconjunction with end pieces each hav ing only one driver passage, orwith end pieces which do not have upwardly yieldable wiping members. Itis also to be understood that such laterally yieldable wiping membersmay be used in a construction where there are no detachable end pieces.

Having described the invention, what we claim as new and desire tosecure by Letters Patent of the United States is:
